Crafter Blue Mechanic Ocean watches

The Crafter Blue Mechanic Ocean is a 300 m dive watch from a company that also makes curved-end rubber straps for Seiko, Rolex and Tudor watches. Crafter Blue gave it a helium escape valve and its calibre 3531, a movement the brand says is based on a Seiko calibre and fine adjusted and decorated by Crafter Blue.

The steel case is 45 mm across and 15.8 mm thick, under a sapphire crystal, with a rotating bezel graduated from 0 to 60. Crafter Blue paired it with its own bi-colour rubber strap, punched with 15 holes for flexibility in length and closed by a 316L steel buckle and keeper.

The MOSS002.SB references have a blue dial and the MOSS008.O references a grey one. The R and RB versions of each share the same case, bezel and dial.

In October 2024 Crafter Blue opened pre-orders for the Mechanic Ocean Mark II, at 41 mm wide and 13.5 mm thick against the 45 mm and 15.8 mm of the MOSS references. It is also rated to 300 m, and uses a Miyota 9015 movement at 28,800 vibrations per hour, a domed sapphire crystal, a 22 mm lug width and a DLC-coated bezel insert.
